BACKGROUND AND SUMMARY OF THE INVENTION

Present invention relates to a communication device and a method ofusing it to enable wireless communication between computing devices.

As an example to demonstrate the functionalities and advantages of thecommunication device of present invention, printing support for wirelessmobile devices (e.g. laptops, PDAs, mobile phones) will be described.

Most handheld devices (PDAs, mobile phones) today do not have printingsupport due to their low processing power and the lack of appropriateprinter drivers. One current method of printing wirelessly from mobiledevices such as PDAs or mobile phones requires that a user first installan appropriate printer driver corresponding to a device specificprinter. One driver is required for each printer. However, most printerdrivers are unavailable for operating systems that run on PDAs andmobile phones. Furthermore, it is difficult and burdensome for a user toinstall a new printer driver each time printing is attempted at adifferent printer. Also, to print wirelessly, the printer needs to bewireless-enabled. Most printers today are not wireless-enabled.Therefore, users of handheld device rely mainly on “synching” theirdevices with PCs to print. However, “synching” could be difficult when auser is traveling or “on the go.” Concerns over security, privacy, andcomplications in installation processes discourage mobile users fromsynching with PCs in a business lounge, hotel business center,conference center or another person's office.

Wireless communication standards such as WiFi and Bluetooth “cut thewire”, allowing the transfer of files between computing devices.Currently, however, privacy and security concerns dictate that a firstcomputing device sending, transferring, or retrieving file or datawirelessly to and from a second computing device (e.g. to its harddrive) requires that the user of the second computing device respondwith an accept or reject command each time (e.g. through a userinterface). This current method or process sacrifices the ease of usefor wireless devices to safeguard security.

Another difficulty in using wireless communication today is that a useris expected to have technical knowledge of the installation andconfiguration of the wireless hardware and software (e.g., adapters,dongles, drivers, protocol stacks), and related security settings. Thecommunication device of present invention significantly simplifies theconfiguration of wireless communications, making it much easier to use.

A communication device of present invention includes a structural,external interface (e.g., a USB interface) for connecting to a computingdevice, a wireless interface for making a wireless connection to asecond computing device, and a memory or storage component for storingand embedding software for a variety of applications. The presentinvention provides wireless printing without the need to install adevice specific printer driver each time at each new location forprinting. Moreover, the invention enables wireless printing to anyprinter—not just to wireless printers. Furthermore, the presentinvention improves the above processes without compromising security orprivacy. The present invention enables transferring of files and datawirelessly from one device to another and improves ease of use.

The communication device of present invention can be connected to afirst computing device (e.g., a personal computer or PC) to enableinstant wireless communication with a second computing device. No driveror software installation is needed in the first computing device. Allsoftware components required to enable the wireless communication areembedded in the communication device itself and can be automaticallylaunched, installed and execute such as through an AutoRun process inthe first computing device.

In addition, the embedded software components in the communicationdevice can automatically uninstall or delete applications or data whenthe communication device is unplugged from the external port such as theUSB or FireWire port. No data from the second computing device or fromthe communication device will be retained in the first computing deviceafter the communication device is disconnected from the first device,thus enhancing privacy and security.

The present invention further allows a computing device to wirelesslyprovide services to other computing devices. As an examples of such aservice, a PC can provide printing or data display services to a mobilecomputing device (e.g., a mobile computer, digital telephone, or digitalcamera). For example, a user of the mobile computing device can simplyplug the communication device (e.g., size of an adapter or dongle) intoa USB interface or port of the PC. The user can then instantly send adocument or data over a wireless connection, through the communicationdevice and to a printer connected to the PC, all directly from themobile device. After the printing process has been completed, thecommunication device is unplugged from the PC and no data is retained bythe PC. No printer driver installation is needed in the mobile deviceand the user can print to any printer that is connected to the PC. Inaddition, the printer need not be a wireless printer.

The wireless communication device of the present invention providesnumerous advantages and functionalities.

Printing documents from mobile devices is made easy. Presentcommunication device simplifies the user experience of data output froma mobile device. A user only needs to connect the communication deviceto a desktop PC or laptop or other computing device (e.g. through USBport). An embedded application in the communication device may beautomatically launch in the PC. The user launches a client applicationon the mobile device (e.g. PDA, mobile phone, digital camera etc) canautomatically recognizes the service (e.g., printing) enabled by thecommunication device of present invention. The user just needs to selectthe document to be printed and the document is printed to a selectedprinter associated with the PC. Thus, wireless communication device ofthis invention simplifies the process of getting a print from the mobiledevice.

The communication device includes embedded software components thatautomate configuration of wireless connectivity. The presentcommunication device automates the process of configuring the hardware(e.g. installation, un-installation), thus making wireless connectivityeasy to use for non-technical users.

Present communication device can be used as an external disk drive. Thepresent communication device is unique since it may also include storageor memory (e.g. flash Memory) that could cache or store data, inaddition to the wireless communication capability. The memory componentmay be segmented into one or more logical segments such as a public areaand a private area. The public area for example can be reserved for auser to save and retrieve data or files when the communication device isplug into a PC or laptop. In this case, the communication device is usedas an external disk storage drive that a user can easily carry alongwith him.

The present communication device simplifies sending and retrieving ofwireless data from one device another, and makes it easer to use andwithout compromising privacy and or security. Prior art methods requiresuser consent or permission from a second party before a first partycould send or retrieve data wirelessly to or from the computing deviceof the second party. The present invention eliminates this requirementwithout sacrificing privacy and or security.

The present communication device could uniquely be used as a channel fordistributing software products. The present invention ties-up thesoftware functionality inside a communication device thus making it moredifficult for software piracy or cloning of software comparing to otherdistribution channels such as CD.

The present communication device can be configured to retrieve data fromonly the second computing device (e.g. mobile device) of a selectedmobile user, thus eliminating the risk of a third device accidentallyretrieving data from the first computing device when the communicationdevice is plugged into the first communication device.

No data is retained by the computing device where the communicationdevice is connected. In the aforementioned printing scenario, if theuser is using another person's desktop for printing, the user must besure that no document or data is accidentally left on the desktop. Whenusing another person's PC there is always concern that a confidentialdocument could be left on the PC. In the present invention, one or moresoftware components embedded in the device ensure that no data relatingto the output of the digital document is retained by the computingdevice.

The communication device of present invention can include an optionalbattery. This enables the communication device to function on its own,without the need to be connected to a PC to draw power. Therefore, amobile device can send and or retrieve files or data wirelessly to andfrom the memory component of the communication device directly anywhere(e.g., wireless device in the pocket of the user) without the need toplug the communication device to a PC for usage.

Printing is used as an example to illustrate the advantages of thecommunication device of present invention. It in no way constrains thescope of the invention. The communication device can embed differentprograms to provide a variety of functionalities through wirelesscommunications between multiple computing devices such as display,presentation of data, secure wireless data transfer, games, instantmessaging, internet access among others as it will be evident by oneskilled in the art after a reading of the disclosure and its accompanieddrawings.

Additional description and implementations of the present invention willbe apparent from the detailed description of the preferred embodimentthereof, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIG. 1 is a block diagram of one embodiment of a communication device100 of the present invention. The communication device 100 includes astructural interface 110, such as USB (universal serial bus) interface,and a wireless component interface 120. Interface 110 can be anystructural interface including, but not limited, to USB, FireWire (IEEE1394), CF (compact flash), SD (secure digital), parallel, serial, amongothers, that enables device 100 to plug into a computing device 170. Thewireless interface 120 may be implemented using any wireless—medium suchas infrared or radio communication according to any protocol includingbut not limited to Bluetooth, IEEE 802.11a, IEEE 802b(WiFi), IEEE802.11ab, IEEE 802.11g, IEEE 802.11f, IEEE 802.15, IEEE 802.17, ZigBeeamong others.

The communication device 100 includes a memory component 130 that mayinclude volatile memory (e.g., ROM, RAM) and or non-volatile memory(e.g., flash memory, hard disk). One or more software components orapplications (not shown) may be stored in the memory component 130. Thesoftware components or applications stored in the memory component 130may include programs or functionalities that enable device 100 to “autorun” or “auto play” so that, when the communication device 100 isconnected with interface 110 to a computing device 170, the program orsoftware application will be automatically installed, launched andexecuted in the computing device 170, as will be described in detailbelow. The memory component 130 may include a program memory segment 140and an optional separate file memory segment 150. Programs or softwareapplications can be stored or embedded in the program memory 140. Thesoftware programs or applications may or may not be viewed or edited(e.g., added, deleted or changed) by a user. Hence program memorysegment 140 can be implemented as a private or secure section of thememory component 130.

As an optional feature, file memory segment 150 may provide foradditional file or data storage, run time buffering of data, or cachingof data and files for faster access. The file storage component 150 isan example of an implementation of such memory segmentation. Thiscomponent 150 may be optional and may or may not exist depending onimplementation. Files and data stored in the file storage memorycomponent 150 typically can be saved, retrieved, viewed or edited by auser through a computing device. As an example, the communication device100 can be used as an external disk drive (e.g., “Flash drive”) that auser can access and use as separate data storage drive when device 100is plugged into the computing device 170.

The communication device 100 may include an optional external controlswitch 165, which can be used to activate, deactivate, control or adjustone or more functions provided by the device. The communication device100 may also include an interface or status indicator (not shown) suchas an LCD displaying text or image, lights or sound for statusindication.

As is known in the art, wireless interface 120 may include a radio, abaseband controller and separate internal memory (not shown). Theseparate internal memory, implemented with Flash, RAM and or ROMcircuitry, can store instructions and data required for properfunctioning of the wireless component 120, such as a wireless protocolstack. Wireless component interface 120 may include a internal processor(not shown) that implements the instructions and logic for complyingwith wireless protocols (e.g. Bluetooth or IEEE 80211, a,b,g,f, amongothers), in addition to managing the radio and the baseband of thewireless component interface 120.

Computing device 170 (e.g. PC, laptop, server) includes at least onestructural interface 172 to which interface 110 of communication device100 is connectable. In a typical implementation, structural interface172 is a USB interface, however other interfaces such as parallel,serial, Firewire (IEEE 1394 a, 1394 b), CF (compact flash), SD (securedigital), Ethernet or wireless interfaces can also be implemented. Tosimplify the following description of the invention, interfaces 110 and172 will be referred to a USB interfaces. It will be appreciated,however, that interfaces 110 and 172 could alternatively be implementedwith any other interface format.

A computing device 180 (e.g., PC, laptop, server, PDAs such pocket PC,Palm, Symbian, Java or Linux cell phones, digital cameras, etc.)includes a wireless interface 182. The communication device 100 cancommunicate with the computing device 180 via wireless interface 120.Examples of wireless interface 120 that can be implemented includeBluetooth, IrDa, ZigBee, IEEE802.11 A, B, F and G, among others.

FIG. 2 is a block diagram of another embodiment of a communicationdevice 200 of the present invention. Elements of the communicationdevice 200 that are common to or the same as elements of communicationdevice 100 are indicated by the same reference numerals. In addition,the communication device 200 includes a controller 260, which maycomprise of a microprocessor. Other implementations of the controller260 are and may include a digital signal processor (DSP), asystem-on-a-chip (SOC), FPGL, ASIC etc. In this implementation, thememory component 130 may also store programs to be executed by thecontroller 260. Examples of functionality and components operable bycontroller 160 may include any combination below and are not limited to:

-   -   A communication protocol stack component (e.g., USB interface or        Bluetooth stack, data or format conversion).    -   Communication and or security management software (e.g.,        protocol encoding/decoding, encryption/decryption, and        authentication).    -   Control modules and components for managing the radio and        baseband component of wireless interface 120.    -   AutoRun components that provide and control automatic        installation and launching on the computing device 170 of one or        more programs stored in 140 when the device 100 is plugged into        computing device 170.    -   Control and management of the structural interface 110 (e.g.        USB, FireWire etc)

The controller 260 may or may not include an operating system. Anadvantage of the implementation of communication device 200 in FIG. 2 isthat it may have a reduced chip count or hardware component costcompared to some implementations. For example, the functionalities ofmultiple components of a communication device of this invention may beimplemented and managed with a single processor in the controller 260,rather than employing multiple controller/processor implementations.

FIG. 3 is a block diagram of another embodiment of a communicationdevice 300 of the present invention. Elements of the communicationdevice 300 that are common to or the same as elements of communicationdevice 100 are indicated by the same reference numerals. In FIG. 3, thememory component 130 acts and may include a hub for the wirelessinterface 120. Memory component 130 may include a controller orprocessor (not shown). In FIG. 1, the wireless interface 120 and memorycomponent 130 are connected to the USB interface 110.

As discussed, memory component 140 can be implemented depending on theapplication. All above features and requirements can be implemented in asingle memory component 130, segmented in to two components 140 and 150,or segmented into three components 144, 146, and 150 as illustrated inFIGS. 4 and 5.

FIGS. 1-3 show memory component 130 segmented into two sections, privatesection or program section 140 and public section or file storagesection 150. The public file storage component 150 corresponds to memorythat can be accessed by the end-user. This optional component 150 allowsa user to save and retrieve data when device 100 is plugged into the USBinterface of computing device 170. This public memory section 150 (e.g.,flash) can also be exposed for public wireless access. Program memorysection 140 is private and end user cannot access it.

FIGS. 4 and 5 illustrate as additional implementations respectivecommunication devices 400 and 500 of the present invention. Elements ofthe communication devices 400 and 500 that are common to or the same aselements of communication device 100 are indicated by the same referencenumerals.

In communication devices 400 and 500 private memory component 140 issegmented into two sections: internal section 144 and embedded section146. Internal memory section 144 can store data and programs requiredfor proper functioning of the communication device 100. These programsand data can be accessed by a memory controller 415 and support itsfunctionalities. Embedded memory section 146 can store programs,applications, and data that will be installed or launched on computingdevice 170 when communication device 100 is plugged into computingdevice 170. The software program or applications typically may not beviewed or edited (e.g., added, deleted or changed) by user and isembedded during the manufacture of devices 400 and 500.

Memory controller 415 manages communication with the structural externalinterface 110 (e.g., USB, FireWire, etc.) and memory component 130.Memory controller 415 can be implemented with a microprocessor, DSP,ASIC, etc and may include internal memory for running its program.Additional memory such as those provided by internal memory section 144can also be implemented if needed. Examples of the functionality andsoftware components that may be implemented with the memory controller415 include “auto run” or “auto play” functionalities, segmentation ofmemory 130, data security, and USB interfacing functionalities, amongothers.

Communication device 400 includes a hub component 425 (e.g., a chip),which combines the components of wireless interface block 120 with thememory component block 130 and its memory controller 415. The hub 425enables sharing of the same external structural interface 110 (e.g.,USB, FireWire) between wireless component 120, memory controller 415 andmemory component 130.

FIGS. 1-5 each illustrates an optional battery 167 being included in therespective communication devices 100-500. Optional battery 167 enableseach of communication devices 100-500 to receive or send data wirelesslywithout being plugged into a computing device 170. Typically, eachcommunication device 100-500 draws its operating power computing device170 when plugged into its interface 172 (e.g., USB).

Communication devices 100-500 of the present invention provide users ofmobile devices 180 (e.g., wireless enabled digital camera, mobile phone,etc.) data storage that is integral with the wireless communication andmay be independent of computing device 170. In accordance with thepresent invention, each of communication devices 100-500 can beconfigured to communicate in a point-to-point manner with awireless-enabled mobile device 180 (e.g., a Bluetooth digital camera,phone etc). An embedded application (not shown) stored on each wirelessdevice 100-500 can manage the communication with an embedded applicationin the mobile device 180.

FIG. 6 is a flow diagram of a wireless external data storage process 600providing data storage that is integral with wireless communication. Thefollowing descriptions refer to “communication device 100-500” as asingular device to emphasize that the referenced communication devicecould be any implementation of a communication device of the presentinvention.

In step 602, a wireless communication channel is established betweenmobile device 180 and communication device 100-500. This step mayinclude additional steps of negotiating the service options between anapplication in the mobile device 180 and wireless device 100-500 throughan interface. The interface may be part of an application GUI (GraphicalUser Interface) in the mobile device 180 or as part of a switch ordisplay settings provided by the wireless device 100-500.

In step 604, mobile device 180 obtains or accesses digital content. Forexample, a photo may be taken with a digital camera or camera phone 180and the photo stored into a memory component of the mobile device 180(e.g., flash memory).

In step 606, the mobile device 180 sends the digital content wirelesslyto communication device 100-500 automatically upon a predefinedcondition being met. For example, the predefined condition can be thatthe data storage contained in the mobile device 180 exceeds a certainpreset threshold. The preset threshold can be the maximum storagecapacity of the mobile device 180, any other storage level, or any othercondition.

In step 608, wireless communication device 100-500 stores thetransmitted data into the available memory component 150 of device100-500 for storage. Optionally, communication device 100-500 may return100-500 a signal or other type of indication to the user of the mobiledevice 180 if the capacity of memory capacity in communication device100-500 is reached.

In step 610, communication device 100-500 is plugged into a computingdevice 170, the data stored in the wireless device 100-500 istransferred to, synchronized with, or stored in the computing device 170(e.g., on a hard drive). For example, this step may be performed by anembedded application that automatically launches and runs on thecomputing device 170. This step may be automatic, or partially automaticor manually aided by the user through a GUI that runs in the computingdevice 170.

In step 612, the data storage area 150 can be cleared manually by theuser, automatically or a combination after the digital content has beentransferred to computing device 170, thereby enabling communicationdevice 100-500 to wirelessly receive additional data from the mobiledevice 180.

FIG. 7 is a flow diagram that illustrates an exemplary method or processof using a communication device 100-500 of present invention.

In step 710, the communication device 100-500 is connected to computingdevice 170. For example, the connection may use a USB interface orFireWire interface.

In step 720, communication is established between the device 100-500 andcomputing device 170. For example, the device 100-500 engages dialogwith the computing device 170 using one or more standard protocols thatare built-into the operating system of the computing device 170 (e.g., a“Plug and Play” feature for USB, and others). In this implementation,the device 100-500 is immediately recognized by the computing device 170once the connection is made (i.e., no driver or software installation isrequired). Alternatively, software such as a driver for setting-upcommunication between the device 100-500 and the computing device 170may be provided to a user separately (e.g., on a CD or downloaded from anetwork) if the operating system of the computing device 170 does notinclude an immediate plug and play feature. In this case, a userinstalls the software in the computing device 170 so that the device100-500 can be recognized.

In step 730, one or more applications stored in the memory component 130may be automatically installed and launched in the computing device 170when the device 100-500 is connected to the computing device. Theinstallation and launching of the application that is embedded or storedin the communication device 100-500 may be implemented using the “AutoRun” or “auto play” feature, which may be provided by the operatingsystem or software installed in the computing device 170 toautomatically launch the program that is stored in the memory component130 of the communication device 100-500. In one implementation, apointer may be embedded in the dialog between the device 100-500 andcomputing device 170 in step 720. The pointer would point to a setupfile in the memory component 130 that instructs the computing device 170to install or run one or more applications stored in the memorycomponent 130. Operating systems can also provide certain means to addentries to AutoRun executables. The various different applications thatare stored in the communication device 100-500 may perform various tasksin the computing device 170. For example, they may help manage wirelesscommunication between the computing devices 170 and 180 through wirelessinterface 120, perform presentations (e.g. Powerpoint™), or perform anyof numerous other tasks or operations, some of which are described laterwith reference to FIGS. 10-16.

In step 740, which is an optional step, a user interacts with thelaunching of an application from the memory component 130 or thesubsequent execution of the application on the device 170. As oneexample, optional user consent or acceptance may be obtained before theapplication is installed and run in the computing device 170. As anotherexample, a user may control the execution process of the application,such as giving command to initiate, pause, cancel, or abort theapplication. User interaction options can be implemented by a GUI(graphical user interface) provided (1) locally in the computing device170, or (2) remotely from another computing device 180 through wirelesscommunication associated with controlling/interacting with theapplication stored in the communication device 100-500. In addition, auser may optionally activate/deactivate the communication device 100-500or one or more of its functions by using the external switch 165 ifthose options are implemented.

In step 750, if the communication device 100-500 is disconnected fromthe computing device 170, a disconnection signal is received orintercepted by one or more applications launched in step 230. In oneimplementation, these applications can automatically uninstall theapplication or applications from computing device 170, and includingitself or themselves and may delete any data stored thereon. In thiscase, no data from the computing device 180 will be retained in thecomputing device 170 after the communication device is unplugged, thusenhancing privacy and security.

Uninstalling all applications and deleting all data residing incomputing device 170 when device 100-500 is disconnected from computingdevice 170 has the advantage of ensuring privacy for a user of computingdevice 170 and also protects the manufacturer of the device 100-500against piracy of the software applications launched in step 730. Thecommunication device 100-500 in this case functions as a security key.When device 100-500 is no longer plugged into the computing device 170,all software applications previously launched can be uninstalled and alldata may be deleted—restoring the computing device to its initial stateprior to the device 100-500 being plugged in.

Step 750 can also be implemented in various ways, depending on the typeof application. When device 100-500 is disconnected from computingdevice 170, the one or more applications launched in step 830 can alsobe configured to uninstall applications and delete data only in part sothat only certain application modules and data are removed. Oneadvantage of this implementation is that when communication device100-500 is again plugged into computing device 170, some installationand setup processes can be skipped and the application will launchfaster. As another alternative implementation, all applications and datacan be retained in the computing device 170 when communication device100-500 is unplugged. This may be preferred in certain cases such as ifprivacy and security is not an issue.

FIG. 8 is a flow diagram of another exemplary method or process of usingthe communication device 100-500 of present invention.

In addition to the basic operations described with reference to FIG. 7,the communication device 100-500 of present invention may includeadditional components, means and features for using it as (1) externaldisk drive for storing, transferring, and retrieving user documentsbetween computing devices, and (2) for adding wireless communicationcapability to computing device 170 for communicating wirelessly withother computing devices such as computing device 180. The combination ofthe above features in a single communication device 100-500 enhances theversatility of the communication device of present invention.

In step 810, wireless device 100-500 is plugged into a first computingdevice 170.

In step 820, wireless device 100-500 is detected by the first computingdevice 170 (e.g. Play and Play).

In step 830, a user may perform read or write operations with the filestorage component 150 of the device 100-500 to use it as an externaldrive. For example, user may save digital documents to the file storagecomponent 150 or retrieve digital documents stored in the storagecomponent. Step 830 (designated process A) illustrates the communicationdevice 100-500 being used as an external memory drive aftercommunication has been established between the device 100-500 and thecomputing device 170 such as through a USB interface. No installation ofsoftware or driver is needed for using this feature of the device100-500.

In step 840, the wireless communication means of communication device100-500 is enabled and activated. Software stored in the device 100-500may be automatically installed or launched. For example the appropriatewireless communication protocol stack may be installed or launched inthe computing device 170, if the computing device 170 does not alreadyhave one pre-installed. Such protocol stacks may be automaticallylaunched and installed in the computing device 170 as one of theapplications stored in the program memory component 140. User may or maynot need to interact with this installation process. In this example,the communication device 100-500 automatically adds wireless capabilityto the computing device 170 by just plugging in the device 100-500.

In step 850, the computing device 170 may now interact with otherwireless enabled devices through the wireless interface 120 of device100-500. The wireless communication may be enabled with an additionalservice discovery and selection step. Steps 840 and 850 (designatedprocess B) show the communication device 100-500 having the means forbeing used as a wireless communication adaptor (e.g., a Bluetoothdongle).

In step 860, an application stored in communication device 100-500 isautomatically installed in computing device 170 and launched. In step870, a query is made as to whether the communication device 100-500 isdisconnected from computing device 170. If no, step 870 returns to step860. If yes, step 870 proceeds to step 880. In step 880, the applicationis terminated automatically. Steps 860-880 (designated process C)correspond to an autorun functionality described above with reference toFIG. 7.

The communication device 100-500 of the present invention may includeany or all of process A (step 830), process B (steps 840-850), orprocess C (steps 860-880) concurrently or in any combination (e.g. A, B,C, A&B, A&C, B&C, or ABC) for one or more implementations of the device100-500. For example, an application that is stored in the programmemory component 130 of the communication device 100-500 may be launchedand executed in the computing device 170 to perform certain tasks (e.g.send and/or receive message from other computing devices, or printingdigital document to a printer connected to device 170). The applicationmay require that the communication device 100-500 stay connected forinteraction with other computing devices through the wireless interface120 (e.g. to receive user command from computing device 180). In thisexample, both process B and process C are required and used.

Conventionally, whenever a first computing device sends, transfers, orretrieves a file or data wirelessly to or from a second computingdevice, a user must manually issue an accept or reject command forsecurity and privacy reasons. The present invention improves upon such aconventional process without sacrificing security or privacy.

FIG. 9 is a flow diagram of a wireless communication process 900 thatmaintains security and privacy without requiring users to manuallyaccept or reject actions, thereby making wireless communication easierto use. Process 900 combines processes A, B, and C for transferringfiles and/or data wirelessly from one device to another.

In step 902, wireless communication device 100-500 is plugged into afirst computing device 170 (e.g., step 810).

In step 904, wireless device 100-500 is detected by the first computingdevice 170 (e.g., step 820), and a wireless application stored in memorycomponent 130 is automatically launched such as through the process ofAuto Run (e.g., step 860).

In step 906, the wireless application enables the communication device100-500 to send and receive wirelessly data to and from another device180 (e.g., step 840). A discovery process may be included in this step.The user of device 180 can then wirelessly transfer (e.g., send, receiveor retrieve) a document from his computing device 180 (e.g., mobilephone, digital camera, PDA, laptop, etc.) to the communication device100-500.

In step 908, computing device 180 can send or retrieve data to or frompublic storage component 150 of the wireless device 100-500 without theneed for the user of the first computing device 170 to respond or grantpermission (e.g., step 850, process B). The public storage component 150of the wireless device 100-500 may be configured to be public, andwireless device 100-500 is connected externally to the computing device.This is in contrast to the hard drive of the first computing device 170,which is private to the user of the first computing device 170. Data istransferred to and from mobile device 180 with communication device100-500 and not directly to and from the hard drive of the computingdevice 170.

In step 910, the user of the first computing device 170 can receive datasent from the second computing device 180 by retrieving the data or filereceived from computing device 180 and stored in the public storage area150 of device 100-500 (e.g., step 830, process A).

Alternately, in step 912, if the user of the first computing device 170desires to make available or public certain data or files for a secondcomputing device 180, he can simply copy the data or file from hiscomputing device 170 to the public storage area or component 150 ofcommunication device 100-500 (e.g., step 330). The files and data in thepublic area in the communication device 100-500 become available forother users, and the second computing device 180 can now retrieve thefile wirelessly from the public storage area of the memory component 150in device 100-500 (e.g., step 850, process B).

In step 914, wireless device 100-500 is unplugged and the applicationthat was launched in the computing device 170 may be uninstalled and alldata may be totally or partially deleted (process C)

FIGS. 10-16 illustrate additional exemplary implementations ofcommunication devices 100-500 according to the present invention andvarious applications that may be stored in the memory component 130 canbe launched for execution and processing in the computing device 170.

FIG. 10 is a block diagram illustrating a system where the communicationdevice 100-500 is used to enable output of data content from a computingdevice 1020 to one or more output devices 1040 that are connected to acomputing device 1030.

Examples of computing device 1030 include but are not limited to desktopPCs, laptop PCs, tablet computers, servers, PDAs, and handheldcomputers. The computing device 1030 has at least a USB interface, forexample, which can connect to the communication device 100-500 ofpresent invention. Other interfaces are also possible as describedabove.

Computing device 1020 includes, but is not limited to, desktop PCs,laptop PCs, tablet computers, servers, PDAs, handheld computers,Internet information appliances, mobile phones, web pads, digitalcameras, and combinations of these devices. The computing device 1020has at least a wireless interface that can communicate with thecommunication device 100-500 through wireless communication protocolssuch as Bluetooth, Infrared, IEEE 801.11a, IEEE 801.11b (WiFi), IEEE801.11 g, Zigbee, among others. It should be noted that although onlyone computing device 1020 is shown here, the computing device 1030 withthe connected device 100-500 may service more than one computing device1020 concurrently or alternatively or in combination. In this case, theapplication 1010 may provide features such as queuing and spooling.

As discussed earlier, application 1010 maybe launched and executed automatically in the computing device 1030 whendevice 100-500 is connected to computing device 1030. For example,application 1010 may AutoRun when device 100-500 is connected to device1030, with no driver or application installation by the user beingnecessary. In this particular example, the application 1010, afterlaunching in the computing device 1030, may perform one or more of thefollowing operations:

-   -   Establish a communication channel with computing device 1020 and        application 1022. This operation may further include a discovery        process as well as sending of information relating to the        service that computing device 1030 can provide to computing        device 1020.    -   Receive or retrieve digital data content from mobile computing        device 1020. Data content includes still images, documents (Word        processing documents, presentation documents, images, text,        spreadsheets, Web pages etc), video images, and or sound data.        Data content may be received from computing devices 1020 through        wireless communication. Alternatively, the data content can be        retrieved from the file storage component 150 of the        communication device 100-500. In this case, the data content may        have been already stored by the user into the memory component        130 before communication device 100-500 is connected to        computing device 1030, or the data content may be have been        previously received from a computing device (e.g., computing        device 1020) and cached in the memory component 130 temporarily        or permanently due to a previous similar operation on the same        document.    -   Process the digital data received in computing device 1030. This        may include one or more components and operations for:        1. Decrypting/decompressing the received data content (e.g.,        digital document).        2. Parsing or interpreting the data content.        3. Converting the data content to a format suitable for input to        one or more output devices 1040 connected to the computing        device 1030. Converting of the data may be performed by the same        software application, or a separate application may be launched        to perform such data conversion        4. Monitoring and providing information on the output process        (e.g., status, payment information, time left to complete, error        messages, etc.) through a graphical user interface (GUI) on the        computing device 1020 or 1030;        5. Receiving and implementing user instructions to the output        process (e.g., initiate, pause, or cancel);        6. Invoking other applications (e.g. a driver application)        residing in the computing device 1030 to participate in one or        more of the above processes or operations. As an example, a        printer driver or raster image processor application may be        launched to process or convert the data content suitable for        input to a selected output device 1040 associated with or        connected to computing device 1030.        7. Queuing and spooling digital documents if more than one        digital document are received from one or more computing devices        1020. The temporary queuing of the data can be in the memory or        storage component 130 or in the memory or storage in the        computing device 1030.    -   Output the data content received or to be received to one or        more selected output devices 1040 associated with or connected        to computing device 1030.    -   After detecting the disconnection of the communication device        100-500, the one or more programs 1010 may completely or partly        uninstall and/or delete themselves as well as any other        applications launched from the communication device 100-500 to        the computing device 1030. Any temporary data that was not        previously in the computing device 1030 may also be deleted.

In addition to the application 1010 above, the memory or storagecomponent 130 of the communication device 100-500 may include otherprograms (not shown) that can be launched and executed in the computingdevice 1030. An example of such a program is a portion or the entirewireless communication protocol stack that allows the computing device1030 to communicate with other computing devices wirelessly through thewireless interface 120 of communication device 100-500. Another exampleof application 1010 includes components that execute and/or control apresentation program (e.g. PowerPoint®) with the presentation filereceived and being controlled wirelessly from computing device 1020.

The received information may include one or more ofthe following: (1) the number and type of output devices (e.g. printers,display devices and projectors) connected to or associated withcomputing system 1035 that is available for service to computing device1020. (2) The type and quality of service, (3) availability of service,(4) price and billing information among others.4. Transmit data content to computing system 1035.5. Encrypt and/or compress the data content prior to data transmission.6. Receive information from computing system 1035 related to the statusof the output process (e.g., output status, payment requirement, timeleft to complete, error messages, quality of service selected etc.) fromthe application 1010.7. Provide a GUI in the computing device 1020, that enables user ofcomputing device 1020 to (1) select a computing system 1035 among a listof available computing systems discovered for service, (2) select one ormore output devices 1040 associated with selected computing system 1035for providing the output service. (3) Display information on the outputprocess (e.g. status, time left to complete, error messages, etc.)and/or give instruction to adjust the output process (e.g. providepayment, initiate, pause, cancel, change of service etc).8. Transmit user command to the application 1010, whereby allowing theuser to remotely control the output process of computing system 1035from the computing device 1020.

Blocks 1040 represent output devices. Printers, projectors and monitorsare shown as examples of output devices. However, output devices mayalso include TVs, fax machines, multifunctional machines (e.g.printer/fax/scanner), copiers, sound output systems, among others.

FIG. 11 shows a flow diagram for an exemplary data output process 1150(e.g. output or printing of digital document) using the systemconfiguration as shown in FIG. 10.

In step 1160, a user has a document in his mobile computing device 1020that he wishes to print. He connects his communication device 100-500 tothe computing device 1030 such as through a USB interface. As discussedearlier, communication is then established between the communicationdevice 100-500 and the computing device 1030.

In step 1165, application 1010 stored in the device 100-500 is launchedin the computing device 1030. Optionally, if the wireless communicationstack is not already included in application 1010, another program(e.g., which includes wireless communication protocol stack) can also belaunched to allow the computing device 1030 to communicate with otherdevices wirelessly.

In step 1170, application 1022 residing in the computing device 1020interacts with application 1010 launched in the computing device 1030 tomanage or negotiate the data transmission process. User of computingdevice 1020 may select from a GUI in his mobile device 1020 one or moreoutput devices 1040 associated with or connected to the selectedcomputing system 1035 for providing the output or rendering service.Application 1022 may transmit data content 1024 from the device 1020 todevice 1030 through wireless communication link 1015. Application 1022may encrypt and or compress data content 1024 before transmission.

In step 1175, the data content 1024 received by the device 1030 isfurther processed. Such process may include, but not limited to,reading, parsing, interpreting, decrypting, and decompressing the datacontent 1024 received. Process 1175 may also include converting the datacontent to output data format (e.g. print data, image file) suitable forinput to the selected output devices 1040 for output or rendering. Theseoperations may be performed by the application 1010 in the computingdevice 1030. Or alternatively, application 1010 may invoke otherapplications (e.g. printer driver application) residing in the computingdevice 1030 to help in one or more steps in the further processing ofthe digital document 1024.

In step 1180, the further processed data content 1024 and generatedoutput data is then sent to the output device 1040 for printing orrendering.

During the output process, user may obtain information related to theoutput process status through a GUI in the computing device 1020. Theuser may also provide instructions to adjust the output process oroptions through the GUI.

After the output process has been completed, the user may disconnect100-500 from the computing device 1030. The application 1010automatically exits and may remove or uninstall itself from thecomputing device 1030. Any data that was used in connection with theoutput process may also be removed or deleted. No data of the content1024 is left in the computing device 1030, which enhances privacy andsecurity.

FIG. 12 illustrates a flow diagram for another exemplary data outputprocess 1250 (e.g. display or presentation of digital content) using thesystem configuration as shown in FIG. 10.

Steps 1260, 1265, and 1270 are identical to respective steps 1160, 1165,and 1170 shown in FIG. 11.

In step 1275, the data content 1024 (e.g., a presentation file such asin a PowerPoint® format) is displayed or projected by output device 1040(e.g., a projector).

In step 1280, the display of data content 1024 is controlled by device1020. Such control may include, but is not limited to, starting orending the display, going forward to the next page or backward to theprevious page, enlarge or minimize the displayed image. Other exemplaryfeatures include reading notes of the presentation file with mobiledevice 1020, while the data content (without the notes) is projected toa projector 1040 through computing device 1030. A GUI may be provided indevice 1020 for the user to perform the above-mentioned control.

After the presentation process has been completed, the user maydisconnect device 100-500 from the computing device 1030. Theapplication 1010 automatically exits and removes itself from thecomputing device 1030 as well as any data or file that was used inconnection with the data output process. No data of the content 1024 isleft in the computing device 1030.

FIG. 14 is a flow diagram showing an exemplary process 1450 of thepresent invention for wireless output of data content (e.g., digitaldocument printing) using the system shown in FIG. 13. As an example ofan application for this invention, a clerk of a photocopy print shop(e.g. Kinko's® or a business service lounge) may hand a communicationdevice 100-500 to a customer who enters the shop. The customer hasstored in his computing device 1330 a document that he needs to print.The customer just plugs the wireless communication device 100-500 intohis computing device 1330 and easily prints out the document to one ormore printers connected to the computing device 1325 that is availablein the print shop.

In step 1460, a user connects communication device 100-500 to computingdevice 1430 through USB interface or another interface. As discussedearlier, communication and interaction is then established between thedevice 100-500 and the computing device 1330.

In step 1465, application 1310 stored in communication device 100-500 islaunched in the computing device 1330. This may be launchedautomatically such as through an AutoRun process as previouslydiscussed. Optionally, another program or component included inapplication 1310 (e.g., a wireless communication protocol stack) mayalso be launched in the computing device 1330 from the memory componentof the device 100-500 to allow the computing device 1330 to communicatewith other devices wirelessly. In step 1465, application 1310 mayfurther include a discovery and selection of the computing device 1325from among a list of available computing devices available forcommunication. Information relating to the output device 1340 associatedwith computing device 1325 may be received and displayed to the user atthe computing device 1330 so the user can select the output device 1340.

In step 1470, user transmits data content 1335 (e.g., a digitaldocument) from computing device 1330 to computing 1320 through wirelesscommunication link 1315. Application 1325 residing in the device 1320communicates with application 1310 running in the computing device 1330to manage the transmission process. Application 1310 may provide a GUIin device 1330 where the user can obtain information on the outputprocess or interact and control the output process. The application 1310may encrypt and or compress data content 1335 before transmission.

In step 1475, the data content 1335 (e.g., digital document) received bythe device 1320 is further processed. Such processing may include, butis not limited to, reading, parsing, interpreting, decrypting, anddecompressing, raster image processing the digital document 1335received. One or more of these processes may include invoking one ormore other applications (e.g. presentation application, printer driver,viewer software etc residing in computing device 1320). Process 1475 mayalso include converting the digital document to an output data format(e.g. print data, image file) suitable for input to one or more outputdevices 1340 associated with computing device 1320.

In step 1480, the processed data content 1335 or output data is sent tooutput device 1340 (e.g. printer) for rendering (e.g. printing,displaying or projecting).

After the output process has been completed, the user may disconnect thedevice 100-500 from device 1330. Disconnecting device 100-500 triggersthe application 1310 to automatically exit and remove itself as well asthe traces of data relating to the data content 1335.
